Parameter in like clause JPQL

Question

I am trying to write a JPQL query with a like clause:

LIKE \'%:code%\'

I would like to have code=4 and find

455
554
646
...
         


        

Answer 1

I don't use named parameters for all queries. For example it is unusual to use named parameters in JpaRepository.

To workaround I use JPQL CONCAT function (this code emulate start with):

@Repository
public interface BranchRepository extends JpaRepository {
    private static final String QUERY = "select b from Branch b"
       + " left join b.filial f"
       + " where f.id = ?1 and b.id like CONCAT(?2, '%')";
    @Query(QUERY)
    List findByFilialAndBranchLike(String filialId, String branchCode);
}

I found this technique in excellent docs: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/jpa_overview_query.html
